EV800D Focus Extension 67mm

This is a 67mm extension I made so I can see the screen on the EV800D clone googles I just got. The tabs are separate to increase the strength. The profile is pretty good, but it needs a good height raft to prevent minor deformation on the female side from bed heat. It does add some neck strain, but that's better than flying blind. My first attempt was a little loose on the eye piece side, but I was able to deform the slot tabs with a quick poke from a soldering iron and now it is fine.
